Brass Silver-Plated Contact Pin, High Precision Electrical Insert Terminal for Connector, Custom Length, Low Resistance

This brass silver-plated contact pin is made of high-quality H62/H59 brass and features high-standard dense silver plating (plating thickness customizable from 3-5μm), combining high-strength mechanical properties with industry-leading electrical conductivity. Processed via precision turning and centerless grinding, it achieves a dimensional tolerance of ±0.005~±0.01mm, with a mirror-polished surface that is smooth and burr-free, ensuring smooth insertion and extraction without damaging mating components. In terms of core performance, the silver plating enables milli-ohm level ultra-low contact resistance, minimizing loss in signal and current transmission. Meanwhile, it boasts excellent corrosion and oxidation resistance, remaining free of blackening and corrosion during long-term use, and can adapt to a wide temperature range of -40℃~+125℃. With a mating life of over 500 times, it maintains stable connection even with repeated use. Widely applied in electronic connectors, wire harnesses, automation equipment, automotive electronics, precision instruments and other fields, this pin supports full-dimensional customization of diameter, length, plating thickness and other parameters, with fast sampling for non-standard parts. Strictly compliant with RoHS and ISO standards, it is available for delivery within 3-7 days for regular specifications and 7-15 days for customized orders. Tiered discounts are offered for bulk purchases, and full-process quality inspection ensures a factory pass rate of ≥99.9%, providing stable and reliable core support for your electrical connection needs.
